Description

Micropearl M 100 is a high-performance, fine-particle chemical additive designed to enhance material properties in advanced manufacturing. Its primary value lies in providing consistent dispersion and controlled reactivity, which are critical for achieving uniform product quality and performance. This product is essential for industries requiring precise modification of physical characteristics, such as rheology, surface finish, and mechanical strength. Key users include formulators in the coatings, plastics, composites, and specialty chemical sectors seeking reliable additive solutions.

Application

• As a matting agent and texture modifier in high-quality industrial and wood coatings.
• As a rheology control additive and anti-settling agent in paints, inks, and gel coats.
• As a reinforcing filler and processing aid in thermoplastic and thermoset composites to improve mechanical properties.
• As a flatting and scratch-resistant agent in automotive and architectural coating systems.
• As a dispersion aid for pigments and other functional fillers in masterbatch production.
• In the formulation of synthetic leather and artificial suede to create a soft, natural feel.
• As a surface conditioning agent in plastic films and sheets to reduce gloss and improve handling.

Quality Control

Every batch of Micropearl M 100 is manufactured under a strict quality management system to ensure batch-to-batch consistency and performance reliability. Our products undergo rigorous quality testing to ensure compliance with industry standards. Certificates of Analysis (COA) are available upon request, detailing key parameters such as particle size distribution, pH, moisture content, and loss on ignition.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep away from sources of heat and incompatible materials. The product is hygroscopic (moisture-sensitive); ensure the container is resealed tightly after each use to prevent moisture absorption and caking.
